Cast Steel Spring Hanger Stretchers
  Highslide JS
  The order has been placed for the large cast steel stretcher patterns incorporating the spring hangers. The pattern maker has already commenced work on the first pattern. This should be delivered ready for the foundry in about ten or twelve weeks time. The foundry that will pour the casting has yet to be decided.
Combined Frame Stretcher Pattern
  The picture shows the front and the back of the new pattern, collected from expert pattern maker Brian Oldford by our engineer Geoff Turner. This is one of the three major cast frame stretchers incorporating the main spring hangers. The red areas are as they will appear in the finished casting.

The areas painted yellow indicate the parts of the pattern that will be machined to the exact dimensions on drawing SL/DE/22042 ensuring everything lines up with the frames during the ensuing erection process. The black areas are where the core boxes are installed in the mould to form the internal profile. There are 16 pieces which make up the pattern and 3 core boxes. The pattern has two split lines in the mould which means 3 boxes, a drag box (on the bottom), a cheek box (in the middle) and cope (on the top). This is by no means a simple casting. The pattern has been safely placed in store while we await quotes from the several foundries contacted with a view to pouring the casting shortly.
Reverser Body Casting
  Reverser body casting, supplied by Keith Bottomley, only one major item now required to complete the reverser. Further to the order for the cast steel stretcher patterns, we have now learned that the first one will be ready for collection from the pattern maker on November 12th, several weeks earlier than first anticipated.
